BELT-CUTTER.

To all whom it may concern:

Be it known that I, PORTER H. PARKER, a

citizen of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented a new and useful Belt-Cutter, of which the following is a specification.

This invention relates to an improved machine for cutting belts made of leather or other material such as are used in connection with machinery.

An object of the present invention is to provide an improved form of belt cutting machine which is adapted to hold a belt rigidly in position during the cutting operation.

A further object is to provide a belt cutting machine with a holding plate positioned thereabove and which is adapted to compress the belt and hold the same rigidly in place, and to provide a knife in connection there with and which knife is adapted to move in aplane at right angles to the longitudinal axis of the belt and to cut the same in a square and at the same time an even manner.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illus trated, in which Figure 1 is a view in side elevation of improved machine. Fig. 2 is a top plan view thereof. Fig. 3 is a. cross sectional view of Fig. 2.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 designates the base formed "with the bed plate 2 and thedownwardly extending supporting rims 3, the latter being provided with suitable apertures 4 extending therethrough for the reception of holding bolts or lag screws therein.

The bed plate 2 is provided with a longitudinal slot 5 through which is adapted Specification of Letters Patent.

to move the knife blade 6. The upper extremity of the knife blade 6 is provided with a suitable gripping handle 7. The slot 5 is formed adjacent the edge of the bed plate 2, the inner edge of the said slot being sharpened so as to cooperate with the knife blade and to thereby effectually cut any material which is disposed upon bed plate overlying the slot.

The knife blade 6 is provided with an outstanding trunnion 8, the outer extremity of which is screw threaded and adapted to receive a securing nut 9 thereon. The trunnion 8 extends through a slotted aperture 10 formed in the downwardly extending rim or side wall 8 and alloWsthe knife blade 6 to be readily adjusted and at the same time is adapted to support the same in a rotatable manner when locked in its adjusted position.

A compression plate 11 is supported above the bed plate 2 and is adapted to be moved forcibly thereagainst so as to rigidly engage the belt or allied article so as to hold the same rigidly in position during the cutting thereof. The compression plate 11 is provided with a cylindrical groove 12 therein into which extends a flange 13 formed integral with the lower extremity of a threaded rod 14.

A circular plate 15 is rigidly secured to the compression plate 11 by the bolts 16 or similar holding means and is adapted to bear upon the top surface of the flange 13 and to hold the same in the cylindrical groove 12. The threaded rod 14 engages the central portion of an arch construction and is adapted to be supported thereby. The arch construction comprises a centrally disposed beam 17 formed integral with the ends of which and extending downwardly therefrom are the supporting legs 18. The said supporting legs 18 are rigidly secured to the bed plate 1 adjacent the four corners thereof. The central portion of the beam 17 is enlarged as at 19 and is provided with a threaded aperture 20 extending therethrough, which threadedly engages the rod 14. A suitable hand wheel 21 is detachably secured to the upper extremity of the threaded rod 14 and provides means whereby the said rod 14. may be manually rotated for the raising and lowering of the compression plate 11.

Extending transversely of the bed plate 1 and rigidly secured thereto are the guide members 22 which comprise the base .23 rigidly secured to the bed plate, the upstanding plates 2% and the inwardly projecting integral flanges 25. As illustrated in Fig. 1 of the drawings, the said guide members are positioned adjacent the edges of the compression plate 11 and are adapted to prevent the rotation thereof as well as limiting the upward or vertical movement of the same, as the overlying flanges 25 project over the edges of the said plate. The guide members 22 also provide a stop or rest against which the belt vmay be positioned and it is noted in this connection that the said guide members are positioned exactly at right angles to the slot 5 of the bed plate which guides the knife in its downward movement.

When it is desired to cut a belt, the compression plate 11 is raised by manually operating the hand wheel 21 and the belt is then positioned therebeneath and with one of the edges thereof in contact with one of the guide members and the belt so positioned that it extends beyond the knife slot 5. The compression plate is then 'brought forcibly into contact with the belt and is adapted to hold the same rigidly in position. The compression plate extends flush with the side edges of the knife slot 5 whereby a clean and sharp cut edge will be obtained. It is to be noted that in the cutting of belts such as used in connection with machinery, it is of prime importance that the cut extends transversely of the belt and at exact right angles to the longitudinal axis of the belt, as otherwise the meeting ends of the belt will not be held in fixed alinement and the belt will tend to shift transversely of the pulley upon which it is used. The adjustable manner in which the cutting or knife blade 6 is held allows the same to be shifted so as to cut belts of varying widths and thicknesses.

By the use of the compression plate such as I have outlined, the material from which the belt is formed will be compressed at the point adjacent the line which is to be out which will insure that a clean and sharp cutting of the belt will be obtained. The slot 5 in the bed plate is of a width just sufiicient to accommodate the knife blade 6 and to provide a guide during the movement thereof.

The machine as illustrated and described will be an efficient labor and time saver as it will materially decrease the time required for the mending of belts.

Having thus fully described the invention, what I claim to be new and original with me is 1. A cutter comprising a base provided with an elongated aperture in the side wall there of, a knife blade pivotally and adjustably secured within said elongated aperture, a compression plate mounted above the said base and adapted to be moved into forced contact therewith, and a guide member con-' tacting with the end of the compression plate for the guidance thereof and adapted to receive the material to be cut thereagainst.
